7 Claims.

The principal objects of this invention are to provide means by which the iilling can be stripped from a bobbin and at the same time a current of air created, which will bring the various strings of lling into contact with the bcbbin stripper itself; to provide a construction in which the bobbins are fed to a position over the bobbin stripper so that the filling will hang down adjacent thereto; to provide an endless carrier with l0 means thereon for holding the bobbins; to provide said endless carrier in such form that no mechanical power is required to operate it but the operator who puts the bobbins on the spindles thereon also moves the conveyor by hand in a very simple manner to move the bobbins from place to place; to provide a locking bar on the endless conveyor for very easily locking the bobbins in place by hand after they are put on the various spindles and with equal ease unlocking them so that they can be removed, and to provide a very simple and inexpensive means for moving the said bar to unlock it.

Other objects and advantages of the invention will appear hereinafter.

'Ihe device is supported by a frame I to which is fixed an auxiliary frame II extending materially above it. From a motor I2 is operated a rotary collapsible stripper I3. It is provided with a cover of cloth I5. It is mounted at one end in a spring pressed bearing I and at the other in a bearing which is covered by a hinged cap I I adapted to be fixed in place by a thumb nut I8. 5 This cap can be swung back and the projecting shaft i9 of the stripper can be manipulated so that the cloth cover l5 with the lling thereon can be removed. The stripper is then collapsed,

a new cover put on and it is put back into place. 10 Beyond the movable end of the stripper is a spring guard 2l for the same purpose as in my prior application.

Extending part way around the stripper from one end to the other are two guards 22 and 23, 15 both for preventing the depending ends of the iilling from being able to move far away from the stripper. This stripper is operated at such a high speed that air currents are induced in through these guards 22 and 23 close to the stripper and 20 coming inwardly toward the stripper at a point above the guard 22. These air currents cause the filling to descend and be deflected toward the stripper so that practically all of them engage the stripper. 25

On the frame Ii are carried pulleys 25 which support a conveyor` in the form of a pair of belts 26 which are connected together, as will be seen. Pulleys loosely mounted so that they are easily rotatable carry the belts. The conveyor is forced 30 upwardly at the center for tension by a pair of idler pulleys 25a adjustably supported by their central pins 2 on a bracket 23 which is fixed to the frame II. This conveyor is not operated by power but is pulled by hand by the operator who stands at the left side of the machine, as indicated in Fig. 2.

The belts 26 are provided with cross bars 39 each of which is provided with a row of pins or spindles 3l each one for receiving a bobbin with its base resting on the bar 30. It is necessary to lock these bobbins in place, as will be seen. For this purpose a guide 32 projects upwardly from the bottom of each bar 3l] and is provided with a horizontal slot 33 in which is located a locking bar 34 that is capable of sliding in and out, as will be seen from comparison of Figs. 8 and l0. This locking bar, when it is pushed out as in Figs. 9 and 10, engages the heel of the 50 bobbin and holds it from displacement even when the spindle 3l extends downwardly. On the bar 3l) are iixed a pair of blocks 35 for assisting in holding the guide in fixed position. Also the bar 30 is provided with a cutout at 36 into 55 which projects an angle iron 3l which is adjustable through a slot 38 across the bar.

A cam 29 is set across the cutout 3S and is'provided with a slanting surface for cooperating with the angle iron 31 to push the locking bar 31% inwardly, as shown in Fig. 10, to lock the whole line of bobbins. This locking bar 3s is pushed inwardly by this cam but as it is moved longitudinally by hand, preferably, although mechanism could be devised for operating it.

There is a similar arrangement at the other side of the machine for releasing this locking bar and thereby allowing the bobbins to fall out when they are arranged bottom side up. This action is accomplished by a cam 32. The locking bar is held in unlocking position yieldingly by a spring 4U carried by a post il mounted on the bar 3E) and projecting outwardly from the conveyor.

In operation, the operator, with one hand, moves one of the bars 30 along in the direction of the arrow in Fig. 2. When they come to the position shown in that figure, stops t3 stop the carrier. At this point the operator supplies bobbins which have come from the loom to the various spindles'on the bar 3K5. They can be put on very rapidly. Now the operator pushes the locking bar in the direction of the arrow in Fig. 6. This locks the bobbins and unlocks the bar from the stop 43. Then the operator grasps one of the belts again and moves the carrier until the bobbins which have just been placed in position come to the downwardly extending or stripping position fully shown in Fig. 2. At that point the iilling is partially unwound, of course, and will usually get into the air currents and on the stripper while the usual operation is performed.

The next time the bobbin holding conveyor,

Ywhich is moved from one station to another,

moves the bobbins just referred to, they come into contact with the cam d2 and are dislodged into a receiver or box 46. In the meantime the bobbins have been released by the fact that the locking bar 34 has been operated against the cam 42 and moved back to the position shown in Fig.

'7, leaving the bobbins free to drop off.

It will be seen, therefore, that this machine can be run by one'operator at whatever speed he is able to operate it. Therefore, the maximum value of the work is obtained. The bobbins: areput in place by hand and held by the locking bar in a very convenient manner. Also the release of the bobbins by the motion of the locking bar is very simple and involves Very little mechanism. This machine constitutes a means for stripping the bobbin with an extremely small amount of labor and also it is a very inexpensive machine to build. The only power required is enough to rotate the stripper at a high speed. The feed of the bobbins is unique and practical.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

l. In a bobbin cleaning machine, the combination of a rotary stripping roll, means for supporting the roll at one end capable of allowing the roll to be turned upwardly about its extreme end, and a support for the roll at the other end having a hinged cap which can be turned back to allow the stripping roll to be tipped upwardly about its rear end for stripping the cloth and filling therefrom by hand.

2. In a bobbin cleaning machine, the combination of a rotary stripper having a textile surface, means for rotating said stripper on its axis, and deflectors adjacent to the stripper and so placed as to cause the rotation of the stripper to induce currents of air in such a direction as to draw the lling descending from the bobbins t0- ward the surface of the stripper.

3. In a bobbin stripping machine, the combination of a rotary stripper, a motor connected to rotate said stripper, a shield extending substantially in a radial direction toward the stripper but spaced therefrom, and a second curved shield, extending around a part of the stripper on the opposite side and converging toward it near the bottom, for the purpose of inducing air currents to blow depending lling into contact with the stripper.

4. In a bobbin cleaning machine, the combination of an endless carrier comprising two endless belts, pulleys for supporting said belts, cross bars on the belts for holding them together, a series of spindles projecting outwardly from each cross bar for receiving the bobbins, and a locking plate on each cross bar for engaging the bobbins beyond their butts to keep the bobbins in position when they are moved by the carrier to a vertical position at the bottom of the carrier.

5. A locking device for bobbins on a bobbin cleaning machine comprising a supporting bar adapted to be moved by hand, a series of spindles on the bar for receiving bobbins, a locking bar movable in a path in which it is entirely free from the bobbins, and a cam for movingA said locking bar into a position to overlap Athe butts of the bobbins, for the purpose described.

6. In a bobbin cleaning machine, the combination of a pair of endless belts adapted to be operated by hand, a cross bar connecting said belts, spindles on the cross bar on one edge on which bobbins are adapted to be placed, a locking bar reciprocable byhand on the firstnamed bar, and two cams for moving the locking bar outwardly to cover the butts of the bobbins and lock them in position when the bar moves `in one position and for moving the locking bar inwardly in the other direction to release the bobbins so that they can be exchanged for others.

7. In a bobbin cleaning machine, the combination of twoendless belts together constituting a carrier, cross bars connecting them so that they will move together, `spindles on the cross bars on which bobbins are adapted to be placed, a locking bar on each cross bar movable by hand, yielding means for holding the locking bars back Vaway from the'bobbins and two camsfor moving the locking bars in opposite directions at theend of their strokes to lock the bobbins so thatthey will not be discharged from the machine and tounlock the bobbins respectively.
